Description

Technical Field

[0001] This utility model relates to the field of oil separator technology, specifically to a micro filter structure for an oil separator. Background Technology

[0002] An oil separator separates the lubricating oil from the high-pressure steam discharged from a refrigeration compressor to ensure the safe and efficient operation of the unit. Based on the principle of reducing airflow velocity and changing airflow direction, oil particles in the high-pressure steam are separated under the influence of gravity.

[0003] The specification of an oil mist separator filter structure in the prior art (publication number CN213790283U) mentions that "the filter cylinder assembly includes filter rings, support rods, and filter screens. There are several filter rings, which are placed vertically on the same axis. The four corners of the inner wall of each filter ring are vertically fixed by support rods. The gap between the filter rings and the support rods is sealed and fixed by the filter screens. The support rods on both sides are equipped with graded filter components. The graded filter components include connecting grooves, locking blocks, compression rods, support plates, springs, connecting rings, graded filter screens, and graded screen units. The support rods on both sides vertically penetrate the connecting grooves, and one end of the locking block is slidably connected inside the connecting grooves." However, the filter structure in the prior art is prone to the accumulation of adhering substances and filter residues, which can clog the filter screens and affect subsequent continuous filtration, making it inefficient and impractical. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a micro-filter structure for oil separators is provided to solve the problem that existing filter structures are prone to adhesion and filter residue, which can clog the filter screen, affect subsequent continuous filtration, and are not efficient and practical.

[0005] To achieve the above objectives, a micro filter structure for an oil separator is provided, comprising an outer cylinder, an upper filter hopper installed in the upper part of the outer cylinder, and a lower connecting pipe provided in the lower part of the outer cylinder. A lower filter pocket is fitted onto the lower connecting pipe, and an upper pad is provided on the upper side of the lower filter pocket. An oil outlet hopper is provided at the lower end of the lower connecting pipe, and multiple guide channels are opened on the inner side wall of the lower connecting pipe. An oil outlet is provided at the lower end of the oil outlet hopper. The upper filter hopper and the lower filter pocket are detachably connected to the outer cylinder.

[0006] Furthermore, a flow-slowing structure is assembled in the upper part of the outer cylinder, and multiple sets of connecting pieces are provided in the flow-slowing structure, with an outlet provided between two adjacent sets of connecting pieces.

[0007] Furthermore, a first motor is installed at the top inner part of the upper filter screen hopper, a first rotating shaft is installed at the upper end of the first motor, and a first connecting plate is fixed on both the left and right sides of the first rotating shaft, and an upper scraper is fixed at the other end of the first connecting plate.

[0008] Furthermore, the inner end of the upper scraper is in contact with the outer ring surface of the upper filter screen hopper, and the upper scraper is inclined.

[0009] Furthermore, the outer ring surface of the upper pad is provided with a first sealing layer, and the first sealing layer is made of rubber material, and the upper pad is connected to the interior of the lower filter bag.

[0010] Furthermore, a bottom plate is provided at the bottom of the lower filter bag, a second motor is installed on the lower end face of the bottom plate, a second sealing layer is provided on the outer sleeve of the second motor, and a second rotating shaft is installed on the upper end of the second motor. A second connecting plate is fixed on both the left and right sides of the second rotating shaft, and a lower scraper is fixed on the other end of the second connecting plate. The outer end of the lower scraper is in contact with the inner side of the lower filter bag.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The purpose of the slow-flow structure in this utility model is to divert the oil entering the outer cylinder to slow down the flow rate. Moreover, the slow-flow structure is easy to assemble or disassemble and can be easily removed for cleaning and reuse.

[0013] 2. In this utility model, the upper filter screen adopts an inverted filter screen structure, which facilitates the oil to flow down from the top, and the filter surface gradually increases. At the same time, the first motor rotates the first shaft, which drives the first connecting plate and the upper scraper to rotate together, which facilitates the upper scraper to scrape off the filter residue on the outer ring surface of the upper filter screen, reducing clogging. In addition, the upper filter screen is also easy to disassemble and remove, which is convenient for regular cleaning and continued use.

[0014] 3. In this utility model, the design of the lower filter bag facilitates a second, more precise filtration of the oil after primary filtration. Inside the lower filter bag, a second motor rotates a second shaft, which in turn drives the second connecting plate and the lower scraper to rotate together. This facilitates the scraping off of adhering substances on the inner wall of the lower filter bag, helping to ensure better filtration of the oil in the connecting pipe and resulting in faster and more precise oil-liquid separation.

[0026] As a preferred embodiment, the slow-flow structure 14 in this utility model is designed to divert the oil entering the outer cylinder 1 to slow down the flow rate. In addition, the slow-flow structure 14 is easy to assemble or disassemble and can be easily removed for cleaning and reuse.

[0027] In this embodiment, a first motor 20 is installed at the top inner part of the upper filter hopper 2.

[0028] As a preferred embodiment, the upper filter hopper 2 of this utility model adopts an inverted filter hopper structure, which facilitates the oil to flow down from top to bottom, and the filter surface gradually increases. At the same time, the first motor 20 rotates the first rotating shaft 21, which drives the first connecting plate 22 and the upper scraper 23 to rotate together, which facilitates the upper scraper 23 to scrape off the filter residue on the outer mesh ring surface of the upper filter hopper 2, reducing clogging.
